The envelope was discovered this morning and had a return address only reading "Tea Party."

Key West police evacuated the entire building, but after investigating the powder determined that it was not a threat.

"Whether this is a hoax or a legitimate threat, this is a serious matter and should be treated as such. Such scare tactics targeted against any elected official, or public servant, will not deter us from serving our constituents, as we will not be intimidated by these cowardly acts," Garcia said in a statement.

Though Garcia's Key West office only has one employee, the entire building was effected. It remained closed today but will be reopen tomorrow morning.
